Here are the newest photos of the Camaro Z28 test mule being tested and directly evaluated against a Mustang GT500. Not only is this a GT500, but it's a 2011 GT500 with Performance Pack! That means it weighs 3750 with 550hp.

GM is making no secret of the benchmark they are attempting to clear -- the 2010 Ford Mustang GT500. This should help put to rest some doubts as to whether this test mule is indeed the range topping Camaro Z28 model expected to be GM's answer to the Mustang GT500.
